Abstract
This paper developed engobe samples for Dan Kwian ceramic body. Kaolinite clay, zirconium silicate, sodium feldspar and quartz were used as raw materials which were varied to obtain various samples. Mix proportion was designed by the square sampling method to obtain 16 samples. All samples were milled and fired at 1200°C under oxidation and reduction atmospheres. The results showed that the suitable engobe composition of kaolinite clay 10 wt%, zirconium silicate 10 wt%, sodium feldspar 40 wt% and quartz 40 wt% to produce good surface appearance for Dan Kwian ceramics. Engobe surfaces and the body had no defect both in the oxidation and reduction atmospheres. The color and engobe surface were opaque white and glossy, respectively.
